A Chemical-Medical Mystery: Gold Jewelry and Black Marks on SkinBarbara B. KebbekusGold jewelry at times makes a black mark or smudge on skin. This may be caused by abrasive powders on the skin (e.g. zinc oxide) but the phenomenon may also be caused by other skin conditions, possibly the presence of chloride ion, acidity, or sulfur-containing amino acids.Kebbekus, Barbara B. J. Chem. Educ.2000, 77, 1298.

A Simulated Growth Hormone AnalysisMary HarrisGrowth hormone is a drug that is sometimes abused by amateur or professional athletes for performance-enhancement. This laboratory is a semi-microscale simulation analysis of a sample of "urine" to detect proteins of two very different molecular weights.Harris, Mary. J. Chem. Educ.1996, 73, 735.

The functioning of vitamins and hormonesWilliams, Roger J.Student interest can be generated by the realization that the functioning of vitamins and hormones are matters that touch their own lives and that diverse problems result from the fact that body chemistries are far from uniform.Williams, Roger J. J. Chem. Educ.1959, 36, 538.
